Custom & Generic Facts

There is great confusion about custom and generic files. Some of our more minor competitors use the word “custom” to describe what they offer without actually knowing what it means… so here are the definitions:

A generic file is one that has a tried and tested calibration created by an experienced file writer who understands the ecu strategy and has tested the calibration on the Road & Dyno before releasing it to the public , there is no need to change it, and it will have been successfully applied to thousands of vehicles with the same ecu and software version. This file only requires to be flashed to the vehicles ECU and datalogged to ensure the vehicle is performing correctly with no need for any revisions or adjustments.

A custom file requires either a Dyno or extensive road datalogging and multiple revisions to the calibration to custom tune to specific hardware upgrades , custom tuning is only necessary when vehicles are running hardware modifications above normal stage 2 requirements , for example hybrid turbos , larger injectors , uprated fuel systems , engine changes such as cams, big valved cylinder heads and so on. Custom tuning takes hours and is a specialised process that requires very expensive master tools and editing software that should be reflected in the price ,many companies claim to offer "custom tuning no generic files" but the reality of it is they don't actually understand the tuning process and are misrepresenting the term , don't be mislead by this marketing ploy !

Mtune will never claim to offer "custom tuning"  we offer tried and tested tuning files.
